Join Zahraa Khalil for an in-depth discussion in this video Wire up the 7-segment LED, part of Learning Arduino: Interfacing with Hardware.
- [Narrator] Alright, so now let's go through the wiring…of the shift register to the seven-segment LED.…I'm going to follow the wiring according to this table.…So on top, you can see the pin letter and the pin number…of the shift register and the corresponding pin letter…and the pin number of the seven-segment LED on the bottom.…So you can choose to connect the seven segment differently…but you need to consider this,…in programming the Arduino board,…so the most significant bit and the least significant bit.…This wiring is for the most significant bit first.…
Alright, so the first one, we need…to connect pin number seven from the shift register…to pin number seven and the seven-segment LED.…Okay, so the very first thing that I'd like to do…is to make sure that since we're using a common anno disk…to get the common pins connected.…So the middle one goes to five volts DCC…and the bottom common pin goes to five volt as well.…
Alright, so the very first pin that I'm going to connect…is pin number seven which is Qh in the shift register…
